Unit 1
What is the difference between qualitative and quantitative data?
Qualitative deals with the 5 senses while quantitative deals with numbers.
What is the relationship between polymers and monomers?
Monomers make up polymers
What two scientists proved that all animals and plants are made of cells?
Theodor Schwann and Matthias Schleiden
What tonicity do plant cells want to be in at all times?
Hypotonic
What is the longest stage of cell division?
Interphase
What is the difference between inferences and predictions?
Inferences are assumptions based on observations while predictions are what you think is going to happen.
What does the polarity of water mean?
The hydrogen atoms are positively charged while the oxygen side is negatively charged.
Who completely disproved spontaneous generation?

How do you collect observations?
With your 5 senses?
What is the difference between cohesion and adhesion?
Cohesion allows water molecules to stick to each other while adhesion allows water molecules to stick to other materials.

What are the 3 parts of the Cell Theory?
1. Cells are the basic units of structure and function in living things.
2. All living things are made of one or more cells
3. All cells come from pre-existing cells, not through spontaneous generation.
